Okay few questions about the tiptronic/speedshift:

1- How many of you guys actually use it on a daily basis?
2- Does it have better fuel consumption than automatic?
3- Is there a right and wrong way of shifting?

Thanks in advance for any comments.

1. I use it everyday.

2. Usually not. The computer can figure out the best shift points given the amount of throttle applied and whatnot, to achieve the best fuel consumption.

3. Yes; in relation to the second question, you have to shift at proper RPMs. For instance, you can't be flooring the car, then shifting up at like 4500 RPM. It will be hard on the clutchpacks.

I realize that. Let me clarify the last question, is there a way you can get the same feeling you would if you were to shift on a standard car? Instead of the smooth shifting to the next gear can't it just shift a little... whats the word... quicker? Perhaps timing the shifting and the gas pedal at a precise timing... I don't know.

i only do that on hwy, or else just leave it at auto

The sportshift/tiptronic WILL shift gears quicker than when on fully automatic mode.

Does this mean that shifting at 4500 when your doing a 0-60 test, that it would be bad on the clutch? I thought the car can handle shifting at 5000 rpm when excelerating quick? No, Yes?

Yes, it can handle it. Shift at the redline.

What I meant was that when you're going WOT and shift prematurely, it's not good for the transmission.

And based on my own experience at the dragstrip, I've had the best results with gate-shifting, fully automatic, and SS -- in that order.

Our SportShift system isn't designed like the SMG for quick shifting and whatnot. It's more for holding the gear while going around corners so you can get the power right away coming out of the turn.

Umm, are you talking about making the computer shift quicker once you've given the command?

Nope. With a stick, you can shift as fast as you can and want. But with the SS, we can't change the shift speed because it's all done by the computer. Yeah, it might be possible that the SS might be programmed to shift faster when in high-RPM range than in low-RPM range. But I don't know the specs or anything on that.

There is a user that has replaced the spring in his transmission (?) maybe in the shifter.. ( don't think so, considering the SS is actually electrically controlled) but basically he said by replacing the spring in the trannie he feels quicker smoother shifts, I think "crisp" is the word he used.. Might be worth looking into if you think the car shifts slow (casually) in SS mode.. pretty sure is wasn't a huge deal, but I might have been wrong, he might have been having his trannie being rebuilt at the time ( making it easy to swap when the trannie is open) but someone would have to help out with the thread and the member that did this.. I'm drawing a blank.

Dow Jones

The sequential shifting is no where near a manual transmission. It's too slow. But this slowness does have one advantage, and that is when you downshift, you actually have half a second to blip the throttle before the actual gear change. This will actually prevent the jerk of the downshift because you bring up the revs before the lower gear engages.

Basically you just downshift and blip. You can even heel-toe at the stop lights or curves if you really want to.

Heh, Is this hard on the tranny?

chewi

i know what u mean...i've done that b4 ...its almost like rev matching...

03SSMTL-S

1.ive used it maybe 4 time since i bought my car in june-04
2. don't know
3. don't know

fsttyms1

it is revmatching and i do it all the time. it makes for alot smoother downshifts and is easier on the tranny, just like in a manual its easier on the clutch (and helps prevent sudden wheel lock up-manual only

You're talking about a shift kit. I know who you're talking about, but I can't remember his user name.
